“DISPOSITIVO DI FISSAGGIO PER UNIRE TRA DI LORO PANNELLI PER ARREDAMENTO” "FIXING DEVICE TO JOIN FURNITURE PANELS BETWEEN THEM"

DESCRIZIONE DESCRIPTION

L’invenzione si riferisce al campo dei dispositivi a giunto per unire fra loro pannelli di armadi, scaffalature o rivestimenti in modo bloccabile e sbloccabile uno rispetto all’altro. The invention refers to the field of joint devices to join together panels of cabinets, shelving or coverings in a lockable and unlockable way with respect to each other.

Il brevetto italiano n. 1169586 descrive un dispositivo di fissaggio che comprende un corpo a tamburo adatto ad essere accolto in apposita cavità in uno dei pannelli da congiungere, in prossimità di un lato di esso, e un elemento a molla a bracci divaricabili, avvicinati fra loro in condizione non sollecitata, i cui bracci fuoriescono dalla parete laterale del corpo a tamburo per impegnare un foro corrispondente nell’altro pannello da congiungere. Il corpo presenta un elemento divaricatore alloggiato fra i bracci della molla e accoglie in modo girevole un elemento a camma di comando che, alla rotazione di esso, sposta la molla fra una condizione estesa in cui i bracci non sono sollecitati dal divaricatore e una condizione retratta in cui i bracci, costretti ad allontanarsi fra loro dal divaricatore, impegnano le pareti laterali del foro del secondo pannello. The Italian patent n. 1169586 describes a fastening device which comprises a drum body suitable to be received in a suitable cavity in one of the panels to be joined, near one side of it, and a spring element with retractable arms, approached together in an unstressed condition , the arms of which protrude from the side wall of the drum body to engage a corresponding hole in the other panel to be joined. The body has a retractor element housed between the arms of the spring and rotatably accommodates a control cam element which, upon rotation thereof, moves the spring between an extended condition in which the arms are not stressed by the retractor and a retracted condition. in which the arms, forced to move away from each other by the retractor, engage the side walls of the hole in the second panel.

Sebbene questo dispositivo precedente abbia dato ottima prova, tuttavia per alcuni impieghi è considerata esteticamente inaccettabile la presenza di una faccia del corpo a tamburo sulla superfìcie del primo pannello. Vi è inoltre una tendenza nel campo verso dispositivi sempre più perfezionati, che possano essere quasi completamente celati alla vista e tuttavia presentino resistenza sempre migliore. Although this previous device has given excellent results, nevertheless for some uses the presence of a face of the drum body on the surface of the first panel is considered aesthetically unacceptable. There is also a trend in the art towards increasingly improved devices, which can be almost completely hidden from view and yet exhibit ever better strength.

Tenendo presente tali obiettivi è stato ideato Toggetto della presente invenzione definito come nella rivendicazione 1. Keeping these objectives in mind, the object of the present invention has been devised as defined in claim 1.

Ulteriori caratteristiche del dispositivo sono dette nelle rivendicazioni successive. Further characteristics of the device are stated in the subsequent claims.

Una camma è accolta in modo girevole entro il corpo e accessibile dallestemo per comandare il movimento avanti e indietro della slitta. In other words, the new fastening device comprises a tubular body suitable to be received at least partially in a first panel and retained therein, being accessible only through the control opening (s) in said first panel: a spring element with retractable arms, received in said body, said spring element overall having a U-shape and the distal ends of the arms forming gripping means; a slide element received and slidable within the body and engaging the connection part of the U of the spring so as to drag said spring for a predetermined stroke between a retracted or working position thereof and an extended or rest position thereof; and viceversa; said body having a fixed retractor which engages the arms of the spring at least in the retracted position thereof and preferably having a protruding protection element or fairing, the profile of which contains the profile of the ends of the arms of the spring in the rest condition thereof. A cam is rotatably received within the body and accessible from the outside to control the forward and backward movement of the slide.

Il nuovo dispositivo è indicato complessivamente con il riferimento 10 nelle figure allegate. Esso comprende un corpo o guscio 12 tubolare, una molla o rostro 14, una slitta 16 accolta entro il corpo, una camma di comando 18. Il corpo o guscio 12 comprende due semigusci, rispettivamente 20, 22. Ciascun semiguscio comprende porzioni di superficie esternamente dentate, indicate rispettivamente con 23, 24, per far presa nelle pareti di un foro di alloggiamento in un pannello. Ciascun semiguscio comprende inoltre un alloggiamento cilindrico ad asse longitudinale, 26, per accogliere la slitta, dotato di pareti di battuta trasversali, rispettivamente 27, 28 Ciascun semiguscio comprende inoltre un foro passante rispettivamente 29 e 30, i due fori essendo allineati nei semigusci montati, per accogliere il gambo dell’elemento a camma 18 in modo girevole. Ciascun semiguscio, o almeno uno di essi, comprende inoltre mezzi a divaricatore 32 che comprendono pareti inclinate, rispettivamente 32’ e che si prolungano in uno stelo 34 terminante con una carenatura o cappellotto di protezione 36. Ciascun semiguscio si prolunga con una parete di protezione 37. I due semigusci comprendono inoltre mezzi di accoppiamento preferibilmente a maschio e femmina su uno e l’altro semiguscio, indicati genericamente con i riferimenti 38 e 40. La slitta 16 comprende due semislitte 16’, 16” accoppiate fra loro mediante mezzi a maschio e femmina o in qualsiasi altro modo opportuno e presentanti un risalto con superfici di battuta 41, 42, per collaborazione con le superfici di battuta 27, 28 dei semigusci. La slitta presenta inoltre un alloggiamento 44 con una forma ad U in pianta per accogliere la parte di collegamento (la parte di unione dei bracci) della molla 14. La slitta presenta poi una camera 45 per accogliere e collaborare con l’elemento a camma 18. The new device is indicated as a whole with the reference number 10 in the attached figures. It comprises a tubular body or shell 12, a spring or ram 14, a slide 16 received within the body, a control cam 18. The body or shell 12 comprises two half-shells, 20, 22 respectively. Each half-shell comprises surface portions externally toothed, indicated respectively with 23, 24, for gripping the walls of a housing hole in a panel. Each half-shell also comprises a cylindrical housing with a longitudinal axis, 26, to accommodate the slide, equipped with transverse abutment walls, respectively 27, 28 Each half-shell also comprises a through hole 29 and 30 respectively, the two holes being aligned in the mounted half-shells, for accommodating the stem of the cam member 18 in a rotatable manner. Each half-shell, or at least one of them, also comprises retractor means 32 which include inclined walls, 32 'respectively and which extend into a stem 34 ending in a protective fairing or cap 36. Each half-shell extends with a protective wall 37. The two half-shells also comprise preferably male and female coupling means on one and the other half-shell, generically indicated with the references 38 and 40. The slide 16 comprises two half-slides 16 ', 16 "coupled together by male means and female or in any other suitable way and presenting a projection with abutment surfaces 41, 42, for collaboration with the abutment surfaces 27, 28 of the half-shells. The slide also has a housing 44 with a U-shape in plan to accommodate the connection part (the joining part of the arms) of the spring 14. The slide then has a chamber 45 to accommodate and collaborate with the cam element 18 .

La molla 14 ha una forma sostanzialmente ad U in pianta con i bracci 47, 48 della U dotati di porzioni 47’, 48’, inclinate per collaborare con le pareti inclinate 32’ del divaricatore. I bracci della molla 14 presentano parti estreme rivolte verso l’esterno, rispettivamente 47”, 48”, eventualmente dentate costituenti mezzi di presa per poter mordere le pareti del foro del pannello da montare. Con 49 si è indicata la parte di unione dei bracci. L’elemento a camma comprende essenzialmente un albero di comando 50 accolto in modo girevole nelle aperture o fori 29 e 30 allineati dei semigusci e nella camera 45 della slitta e una parte eccentrica 52 che collabora con la parete della camera 45. Un foro passante 53 generalmente esagonale è previsto per l’azionamento con una chiave esagonale (non illustrata). The spring 14 has a substantially U-shaped plan with the arms 47, 48 of the U equipped with portions 47 ', 48', inclined to collaborate with the inclined walls 32 'of the retractor. The arms of the spring 14 have extreme parts facing outwards, respectively 47 ", 48", possibly toothed constituting gripping means in order to bite the walls of the hole in the panel to be mounted. 49 indicates the joining part of the arms. The cam element essentially comprises a drive shaft 50 rotatably received in the aligned openings or holes 29 and 30 of the half-shells and in the chamber 45 of the slide and an eccentric part 52 which cooperates with the wall of the chamber 45. A through hole 53 generally hex is intended for operation with a hex wrench (not shown).

Per l’uso, in un primo pannello P1 e un secondo pannello P2 (Fig. 2) vengono praticati dei fori cilindrici, precisamente un foro F1 nel pannello P1 e un foro F2 nel pannello P2, nelle facce di essi destinate a essere collegate una contro l’altra. Si ricava poi fori d’accesso di comando F3 ad asse ortogonale a F1. Il dispositivo 10 introdotto nel foro F, è in esso trattenuto dalle alette o dentellature 24 e 23 dei semigusci ed è accolto in modo da essere sporgente con una sua parte d’estremità che comprende il cappellotto di protezione 36 e le pareti di protezione 37. Durante questa fase la molla è nella sua condizione di riposo illustrata nelle figure 2 e 4, vale a dire con i bracci avvicinati e i mezzi o artigli di presa accolti sotto o dietro il cappellotto di protezione 36. Ciò permette di introdurre l’estremità del dispositivo nel foro F2 senza difficoltà e senza rovinare le pareti del foro. Una volta posizionato il pannello P2 nella posizione voluta rispetto al pannello P1, si introduce la chiave di manovra (non illustrata) nel foro F3, fino ad impegnare il foro di azionamento 53 della camma. For use, cylindrical holes are drilled in a first panel P1 and a second panel P2 (Fig. 2), namely a hole F1 in the panel P1 and a hole F2 in the panel P2, in the faces of them destined to be connected a against each other. It is then obtained command access holes F3 with an axis orthogonal to F1. The device 10 introduced into the hole F is held there by the fins or indentations 24 and 23 of the half-shells and is received so as to be protruding with an end part thereof which comprises the protective cap 36 and the protective walls 37. During this phase the spring is in its rest condition illustrated in Figures 2 and 4, that is to say with the arms approached and the gripping means or claws received under or behind the protective cap 36. This allows the end of the device to be introduced. into hole F2 without difficulty and without damaging the walls of the hole. Once the panel P2 has been positioned in the desired position with respect to the panel P1, the operating key (not shown) is introduced into the hole F3, until it engages the actuation hole 53 of the cam.

La rotazione della camma dalla posizione illustrata nella Fig. 4 alla posizione illustrata nella Fig. 5 ha l’effetto di fare scorrere la slitta 16 dalla posizione contro la parete di battuta 42 alla posizione contro la parete di battuta 28. Questa corsa della slitta trascina con sé la parte di collegamento della molla e costringe le parti inclinate 46 dei bracci di essa a scorrere lungo le pareti inclinate del divaricatore, divaricando così i bracci della molla. Ciò porta gli artigli d’estremità 47, 48 a divaricarsi fuori dall’area coperta dal cappellotto di protezione 36 così da impegnare la parete del foro F2 come si vede nella Fig. 1. Rotation of the cam from the position illustrated in Fig. 4 to the position illustrated in Fig. 5 has the effect of sliding the slide 16 from the position against the abutment wall 42 to the position against the abutment wall 28. with it the connection part of the spring and forces the inclined parts 46 of the arms thereof to slide along the inclined walls of the retractor, thus spreading the arms of the spring. This leads the end claws 47, 48 to spread out of the area covered by the protective cap 36 so as to engage the wall of the hole F2 as seen in Fig. 1.

La manovra opposta della camma, per l’elasticità della molla che tende a riprendere la condizione indeformata, porta ad avvicinare fra loro i rami della molla, che si riporta quindi nella posizione della Fig. 2 e consente lo smontaggio dei pannelli. The opposite maneuver of the cam, due to the elasticity of the spring which tends to resume the undeformed condition, brings the branches of the spring closer together, which then returns to the position of Fig. 2 and allows the disassembly of the panels.

Si noti che preferibilmente la camma presenta il foro 53 passante, così da poter essere azionata da una o l’altra estremità dell’albero 50, a seconda di come sia preferibile per il montaggio. Note that the cam preferably has the through hole 53, so that it can be operated by one or the other end of the shaft 50, depending on how it is preferable for assembly.

Il nuovo dispositivo può essere inserito in pannelli da accoppiare, con un minimo impatto visivo, poiché è sufficiente che resti accessibile dall’esterno il foro F3 corrispondente al foro di manovra 53 della camma sul pannello P1, mentre il foro F2 per accogliere l’estremità del dispositivo è assolutamente invisibile quando i pannelli sono montati assieme. The new device can be inserted in panels to be coupled, with a minimum visual impact, since it is sufficient that the hole F3 corresponding to the operating hole 53 of the cam on the panel P1 remains accessible from the outside, while the hole F2 to accommodate the end of the device is absolutely invisible when the panels are mounted together.

Inoltre il nuovo dispositivo consente una resistenza ottima al taglio e alle sollecitazioni in genere. Furthermore, the new device allows excellent resistance to shear and stresses in general.
